TORNADO Features

TORNADO Sub-Surface aeration eliminates problems of spraying, splashing, and misting of structures, equipment, and personnel, often associated with surface aeration equipment. With TORNADO Aerators/Mixers, you:

• Decrease the potential for foul-smelling odor, immediately near the aeration tanks or beyond the plant to near-by areas communities. This improves employee morale and makes for a neighborhood-friendly treatment plant.
• You reduce or eliminate the potential for unsightly mess, corrosion of equipment, and damage to structures caused by splashing and misting. This can only decrease operating and maintenance costs and safety hazards.

Maximum Oxygen Transfer and Mixing
Every component in the TORNADO Sub-Surface Aerator/Mixer is designed with one objective in mind: the optimum delivery of oxygen into the water and its complete mixing with the water. The benefit to you is substantial savings you can count on.

• The Motor: Each motor used on your TORNADO is energy efficient, certified to meet global standards, and sized for best performance with other components. This means more of the energy consumption goes to deliver oxygen.
• The Propeller: After almost twenty years of experience and thousands of TORNADO's around the world, Aeromix engineers have learned that not any propeller can do the job effectively. That's why, they designed each TORNADO model with a unique propeller that converts the incoming air stream into very fine bubbles in the water and pushes them away for maximum residence time and maximum zone of oxygenation.
• The Draft Tube: The draft tube, which serves to channel the air into the water, looks simple. But after extensive research and field experience, it has undergone several design changes to insure that it provides maximum air flow with minimum pressure drop.

Ruggedness You Can Depend On
Your treatment plant is much too important to get snagged with product failures. That's why we designed and built our TORNADO Sub-Surface Aerator/ Mixers for many years of minimal maintenance and flawless operation. This means your capital budget can carry you further into the future and your annual maintenance expenses are substantially reduced. Consider these benefits:

• The Motor: The motor on your TORNADO is by far the most rugged on the market. It provides you with dependable operation in the severe environments of treatment plants, including the dampest, dirtiest, hottest or coldest plants.
• Motor Coupling: A flexible coupling is used to take up any misalignment between the aerator and motor shafts, eliminating the potential for failure problems.
• Motor Mount: A stainless steel motor mount with two pins allows the aerator to be easily rotated from nearly vertical to nearly horizontal positions, for maximum performance. But at the same time, it is designed to allow removal of either the motor or the aerator, for ease of maintenance.
• The Propeller: Unlike others, our propeller is made of stainless steel for long lasting performance.
• The Shaft: Our shaft is precision machined of heat treated solid stainless steel, supported by two bearings, at the top and at the bottom, inside a unique bearing support and shaft protection tube assembly. This design provides maximum stability, vibration free operation, and unmatched extended life.
• The Bearings: The 100,000 hour- rated bearings are of the tapered roller design that would take up all thrust loads from the propeller, without transferring any part of it to the aerator shaft, coupling, motor shaft, or motor bearings. The bearings operate within a grease lubricated environment and are sealed to protect them against water splashing or submergence.
• The Bearing Support and Shaft Protection Tube: Made of stainless steel, the patented tube serves to support the bearings and protect the rotating solid shaft. Seal modules are used to protect the bearings from the environment.
• The Draft Tube: The draft tube, which serves to channel the air into the water, looks simple. But after extensive research and field experience, it has undergone several design changes to insure that it provides maximum air flow with minimum pressure drop. You get the most aeration and mixing for the least amount of energy; all below the surface of the water without spraying or splashing.

Proven Performance
Today, there are thousands of TORNADO aerators/mixers operating at more than 3000 treatment plants in more than 80 countries. It has been proven time and time again, some for almost 20 years.

The field proven TORNADO delivers dependable and economical performance in almost any condition, and provides superior performance in a wide range of applications.

It is simple to direct aeration and mixing toward a deficient area with the angle adjustment locking bolts. It allows for optimal horizontal mixing velocities and fine bubble-residence time time.

It is fully adjustable whether mounted on a float, bridge, or wall. It allows for aeration and mixing of any basin and tank regardless of depth or shape.
